|[-]parenb||Generate parity bit in output and expect parity bit in input.|
|[-]parodd||Set odd parity (even with -).|
|cs5 cs6 cs7 cs8||Set character size to 5, 6, 7, or 8 bits.|
|[-]hupcl [-]hup||Send a hangup signal when the last process closes the tty.|
|[-]cstopb||Use two stop bits per character (one with -).|
|[-]cread||Allow input to be received.|
|[-]clocal||Disable modem control signals.|
[-]ignbrk Ignore break characters. [-]brkint Breaks cause an interrupt signal. [-]ignpar Ignore characters with parity errors. [-]parmrk Mark parity errors (with a 255-0-character sequence). [-]inpck Enable input parity checking. [-]istrip Clear high (8th) bit of input characters. [-]inlcr Translate newline to carriage return. [-]igncr Ignore carriage return. [-]icrnl Translate carriage return to newline. [-]ixon Enable XON/XOFF flow control. [-]ixoff Enable sending of stop character when the system input buffer is almost full, and start character when it becomes almost empty again.
[-]opost Postprocess output.
[-]isig Enable interrupt, quit, and suspend special characters. [-]icanon Enable erase, kill, werase, and rprnt special characters. [-]echo Echo input characters. [-]echoe, [-]crterase Echo erase characters as backspace-space-backspace. [-]echok Echo a newline after a kill character. [-]echonl Echo newline even if not echoing other characters. [-]noflsh Disable flushing after interrupt and quit special characters.
* Though this claims non-posixhood it is supported by the perl POSIX.pm.
[-]tostop (np) Stop background jobs that try to write to the terminal.
ek Reset the erase and kill special characters to their default values. sane Same as:
cread -ignbrk brkint -inlcr -igncr icrnl -ixoff opost isig icanon echo echoe echok -echonl -noflsh -tostop
also sets all special characters to their default values.
[-]cooked Same as:
brkint ignpar istrip icrnl ixon opost isig icanon
plus sets the eof and eol characters to their default values if they are the same as the min and time characters. With -, same as raw.
[-]raw Same as:
-ignbrk -brkint -ignpar -parmrk -inpck -istrip -inlcr -igncr -icrnl -ixon -ixoff -opost -isig -icanon min 1 time 0
With -, same as cooked.
[-]pass8 Same as:
-parenb -istrip cs8
With -, same as parenb istrip cs7.
dec Same as:
echoe echoctl echoke -ixany
Also sets the interrupt special character to Ctrl-C, erase to Del, and kill to Ctrl-U.
The special characters default values vary from system to system. They are set with the syntax name value, where the names are listed below and the value can be given either literally, in hat notation (^c), or as an integer which may start with 0x to indicate hexadecimal, 0 to indicate octal, or any other digit to indicate decimal. Giving a value of ^- or undef disables that special character.
intr Send an interrupt signal. quit Send a quit signal. erase Erase the last character typed. kill Erase the current line. eof Send an end of file (terminate the input). eol End the line. start Restart the output after stopping it. stop Stop the output. susp Send a terminal stop signal.
min N Set the minimum number of characters that will satisfy a read until the time value has expired, when <E>-icanon<E> is set. time N Set the number of tenths of a second before reads time out if the min number of characters have not been read, when -icanon is set. N Set the input and output speeds to N. N can be one of: 0 50 75 110 134 134.5 150 200 300 600 1200 1800 2400 4800 9600 19200 38400 exta extb. exta is the same as 19200; extb is the same as 38400. 0 hangs up the line if -clocal is set.
-a Print all current settings in human-readable form. -g Print all current settings in a form that can be used as an argument to another stty command to restore the current settings. -v,--version Print version info.
<B>B>stty()<B>B> IO::Stty::stty(\*STDIN, @params);
Im not feeling very inspired about this. Terminal parameters are obscure and boring. Basically what this will do is get the current setting, take the parameters, modify the setting and write it back. Zzzz. This is not especially efficent and probably not too fast. Assuming the POSIX spec has been implemented properly it should mostly work.

This is use at your own risk software. Do anything you want with it except blame me for it blowing up your machine because its full of bugs.
See above for what functions are supported. Its mostly standard POSIX stuff. If any of the settings are wrong and you actually know what some of these extremely arcane settings (like what sane should be in POSIX land) really should be, please open an RT ticket.
